Brace yourselves... this will probably be a long and confusing post. But I will do my best to explain what I'm doing here. I absolutely love to make flags of countries I've visited (I know, it's a little weird) and I have been working on the Norwegian Flag. I've since started a new endeavour -- an Israeli flag since I will study there next year and I calculated the specs. so it comes out to scale for a twin-sized afghan: just as I had done for the Norwegian flag.

My only problem is getting the center to work out with the star.

The finished blanket should be 69.1x95 in and I'm knitting on size 7 needles.

with my calculations that should be about 484 st. x 665 st. *give or take* and should work out divided into the following colour blocks (the overall 69.1x95in needs to be to the scale of 8:11):
white 45 h * 665 w
blue 76 h * 665 w
white 242 h * 665 w
blue 76 h * 665 w
white 45 h * 665 w

That leaves the star which should take up 200 stitches of the 242 white block *height and width* but I'm not sure how I work this into the pattern.

I found a knit chart for the star, but it's a 30x30 square. How do I increase it to compensate for the larger scale I need for my pattern?

I'm fairly new to knitting (and pattern making!) and would appreciate any help. I'm so sorry for the long post. I just wanted to make sure you had enough detail to see where I'm coming from.
